Abstract

The management of images, video, and in general, multi-
media data, is an improtant issue in the design of digital
libraries. In particular, the following problems stand out:
efficient storage, fast retrieval, and protection of intellectual
property. We outline below some of the recent
advances in image processing in the context of the UCSB
Alexandria Digital Library (ADL) project whose goal is to
create a database of spatially indexed data. Maps and satelite
images are among the main data sets in the project.
The focus of this overview is on image retrieval using texture
and on digital watermarking. A texture thesaurus for
browsing aerial photographs and a wavelet based digital
watermarking scheme are presented.
